SuperPro Alloy Front Lower Control Arm Set - Standard Geometry
SuperPro's ALOY014K offers a number of significant upgrades in a single kit.
First the alloy control arms themselves are both lighter and stronger than the steel arms used on WRX models - the ALOY0014K effectively provides an STI-style alloy arm set with upgraded bushings already installed
Second; anti-lift geometry. This keeps more of the tire's contact patch in contact with the pavement under acceleration allowing your power to more efficently get to the ground.
Third; SuperPro's proprietary polyurethane compound and DuroBall compound bushing used in the foward and rearward bushing assemblies offering a massive upgrade over the soft and heavily voided OEM bushings. This reduces deflection and movement resulting in more consistent tire performance - better traction, better grip and reduced wheel hop. The smaller inner bushings at the rear also features a bonded steel shell to reduce any friction during suspension travel to allow your springs and dampers to deliver the intended performance.
Fourth; this kit is complete - including required hardware and new ball joint bosses avoiding the issue with corrosion often making it difficult or impossible to re-use the originals.
Why Standard Geometry? If you're looking for additional positive caster from this control arm upgrade - see our ALOY0015K kit that includes a double offset bushing design to increase positive caster. The standard geometry kit came about for customers who wish to run a significantly lower ride height than stock and/or a much wider wheel and tire package - or simply a more aggressive (numerically lower) wheel offset. The additional caster featured in the ALOY0015K will move the front wheel forward in the wheel opening slightly - normally not an issue, but in cars running very low ride heights, extremely aggressive wheel/tire combinations or some combination of the two - this can cause the tires to rub on the inner fender liner at or near full steering lock (like when backing out of a parking spot. For these customers, we have introduced the ALOY0014K without the additional caster built in.
